He was born in London, the eldest son of the dramatist, Douglas William Jerrold. Abandoning the artistic career for which he had been educated, he began working on newspapers at an early age. He was appointed Crystal Palace commissioner to Sweden in 1853, and wrote A Brage-Beaker with the Swedes (1854) on his return. In 1855 he was sent to the Paris exhibition as correspondent for several London papers, and from that time he lived much in Paris. In 1857 he succeeded his father as editor of Lloyd's Weekly Newspaper, a post which he held for twenty-six years.
During the American Civil War he strongly supported the North, and several of his leading articles were reprinted and placarded in New York City by the federal government. He was the founder and president of the English branch of the international literary association for the assimilation of copyright laws.
Four of his plays were successfully produced on the London stage, the popular farce, Cool as a Cucumber (Lyceum 1851), being the best known. His French experiences resulted in a number of books, most important of which is his Life of Napoleon III (1874). On his death, he was occupied in writing the biography of Gustave Dore, who had illustrated several of his books.
